Cartrophen injections

Benson has just finished a course of Cartrophen injections, a course of 4 injections over a 4 week period. I thought it might be useful to write a few notes on indications for Cartrophen, as well as our personal experiences. :)

When is Cartrophen (active substance Pentosan Polysulphate Sodium) indicated for use?

Treatment of lameness and pain of degenerative joint disease/osteoarthritis (non-infectious arthrosis) in the skeletally mature dog.

This largely depends on the individual dog. In the main, it seems better to use in the early treatment of osteoarthritis in dogs, as part of a multi-modal regime of O/A management. This means weight management, good nutrition as well as dietary supplementation and physiotherapy. Osteoarthritis in dogs is where the joints become damaged through wear and tear, often due to surface irregularities, which can be due to various causes, genetics, trauma, environment for example. Early identification and treatment can really help. Whilst it is really upsetting to hear our dogs have joint problems, having a good care plan in place can make the world of difference. Subtle changes in gait, reluctance to exercise, stiffness, even reactivity can all be symptoms of joint discomfort. The problem with joint discomfort is that it leads to changes in gait, muscle imbalance which in turn can lead to more irregular joint remodelling.

So how does Cartropen work?

Cartrophen works directly on the soft tissue surrounding the joint and is known clinically as a "disease modifying drug" (DMARD) It has a couple of different mechanisms which are known to protect and support the chondrocytes (which work at maintaining a healthy cartilaginous matrix which surrounds the joint) This helps promote a more "fluid" joint.

What advice have I been given alongside Benson's course of injections?

Benson has just finished a four weekly course. We were advised to go gently on the exercise front, and not use NSAIDs if possible, certainly not within 24 hours of injection, this is due to Cartrophen having an anticoagulant effect. We need the injections to do their job, and not encourage too much activity!

So Benson has just finished his first course. His elbows are definitely less tender and his whole demeanour is best described as more "bouncy". A technical term as this is how it has been written in his notes! :dug:

Thank you for this @Beanwood. I need to give this serious thought in the not too distant future for Sky. She is on Rheumocam and we still have the option of upping her dose so that’s our next part of the plan before injections. She is getting very little exercise at the moment after a good amount recently - we let her choose if she wants to go on the walks during the day but she gets no choice about the evening stroll so that’s all it has been. It’s then hard to stop her putting weight on. I’d love her to get a bit of ‘bounce’ back.
 
Obi has recently finished his first course of four injections. He was skipping occasionally with his right hind, and was reluctant to jump up onto the bed sometimes. The skipping has gone away, he’s very happy to jump onto the bed and he’s also taken to leaping into the car (something we don’t encourage!) which he absolutely would not have done previously. So, it’s definitely made a difference.
 
When would you say you noticed at difference with Benson, Beanwood? Our vet says you can often see a change after the second injection.

Is the plan to have another round of 4 injections after 6 months?

Really glad it’s helped Benson. As you say, getting started earlier rather than later is the way to get most bang for the buck.
 
I am so pleased it has helped Benson. I used it years ago on a GSP but it didn't seem to help. I am wondering why my vet hasn't mentioned it for Rourke's shoulders? I see it mentioned good nutrition, what do your feed Benson? Will you have to continue to use Cartrophen as and when?
